To add to the list of "out" gay actors and singers including "Doogie Howser" himself Neil Patrick Harris, TR Knight from "Grey's Anatomy", Luke MacFarlane who plays Scotty in "Brothers and Sisters (currently being shown on RTE1 and E4) has revealed to Canadian newspaper "Globe and Mail" that he is gay.
In the interview he says "I don't know what will happen professionally. That is the fear, but I guess I can't really be concerned about what will happen because it's my truth..."
Firstly congratulations to Luke for coming out publically. It's not an easy thing to do. Hopefully the fact that he has come out shows a growing acceptance and understanding by the wider community.
